Upgrading the MTA128ST-USB with FlashWizard
The MTA128ST-USB has a flash PROM, which contains firmware code for the hardware. At various
times, Multi-Tech may add enhancements and/or fixes to the firmware. The flash technology used in
the MTA128ST-USB lets you load these upgrades into the PROM through the MTA128ST -USB’s USB
port.
